Moe Water Treatment Plant upgrade

Securing water for Moe


The works at the Moe water treatment plant are essential to ensure a reliable drinking water supply by meeting the demands of expected urban growth and development.

The plant upgrade includes improvements to the treatment plant building and equipment, which treats our water to make it safe to drink. The large new 24 megalitre storage basin will provide operational flexibility and increased security of supply.

Following construction of the new basin, the existing storage basin will be upgraded with a new liner and cover. This will further add to the long term capacity and security of the regional water supply.


Update - January 2024

The new basin is now complete. Where about to begin installing a new liner and cover for the plant’s existing basin and new pipework.

Update - July 2023

The new basin is nearing completion, with the basin construction completed and the liner and cover installation underway.

Update - April 2023

The new basin at the Moe water treatment plant is starting to take shape. After the civil construction and internal pipework is complete, a new liner and cover will be installed, followed by interconnecting pipework ready for the basin to be put into service.

Update - August 2022

The upgrade to the plant's treatment system has been completed. Construction of the new 24 megalitre water storage basin has commenced. After the new basin is completed, the existing basin will be given a new cover and lining - this is scheduled for 2024-25.

Fast facts

The upgrades involves:

  • Improving the treatment plant buildings and equipment
  • Constructing an additional drinking water storage basin
  • Replacing the liner and cover of the existing storage basin.

This upgrade will modernise the plant, increase overall capacity and allow future upgrade and maintenance works to be completed without restricting water supply to customers.

More information

The upgrade will:

  • More than double the volume of stored drinking water at the Moe site
  • Cater for growth and development throughout the Moe region
  • Allow for emergency repairs and maintenance without restricting water supplies to customers
  • Ensure the ongoing safety of water supplies in the region

Like with all our works, we want to have as little environmental impact as possible. Things we're doing to minimise our environmental and heritage impacts at the site include:

  • Building the new basin on newly-purchased land. This will reduce the impact on existing bushland
  • Designing the new basin so that there is a minimal construction footprint
  • Undertaking cultural heritage assessments - no artefacts within the planned construction zone
  • Extensive flora and fauna assessments, including owl habitat surveys, within the proposed construction zone
  • Protecting the equivalent environmental values at one of our environmental offset sites when vegetation is removed
  • Implementing construction environmental management plans to ensure no impacts occur outside the proposed site.

We have consulted with neighbouring properties and stakeholders.

We also welcome direct comments and enquiries from the community at any time.
